Custom machining consists of manufacturing or modifying mechanical parts according to a client's precise requirements, rather than producing standard parts.

In practical terms, a company like Ateliers BG can start from a plan or drawing and remove material (metal, plastic, etc.) to obtain the desired shape.

CNC machining (computer numerical control) is a custom machining method in which machines are computer-controlled from a program. It enables very high precision and identical reproduction across multiple parts.

Welding consists of joining metal parts by fusing them with heat, sometimes with filler metal. It is often used to manufacture structures, frames, supports and tanks for industrial equipment.

In an industrial shop such as Ateliers BG, this can include:

• Assembly of steel, aluminum or stainless steel parts.
• Manufacturing of mechanically welded structures (machine frames, conveyors, supports, etc.).
• Assembly of subassemblies before machining or painting.

Common welding processes

• MIG (GMAW): fast and widely used in industrial fabrication.
• TIG (GTAW): more precise, often used for stainless steel and aluminum.
• SMAW (shielded metal arc welding): common for repairs and field work.
• Flux-cored (FCAW): suited to thick parts and heavy fabrication.

Robotic welding is a process in which an industrial robot automatically performs welding operations according to a predefined program.

Instead of a welder holding the gun or torch manually, the robot moves the welding tool with high precision and repeats exactly the same movements on each part.

Benefits

High precision: welds are highly uniform.

Repeatability: every part is welded the same way.

Increased productivity: the robot can work quickly and for long periods.

Reduced defects: fewer variations caused by fatigue or differences between operators.

Improved safety: less direct exposure to heat, fumes and sparks.

Mechanical assembly consists of mounting several parts or components together to form equipment, a machine or a functional subassembly.

In a company like Ateliers BG, mechanical assembly can be the final stage of a turnkey project: after machining, welding and painting, all components are assembled to deliver a product ready for installation or use.

Plasma cutting is a technique used to cut conductive metals (steel, stainless steel, aluminum, copper, etc.) with an extremely hot plasma jet.

Plasma is an ionized gas heated to temperatures that can exceed 20,000 °C. This jet melts the metal, while an air or gas flow expels the molten metal to create a clean cut.

Plasma cutting is used to cut steel plates, manufacture machinery parts, create complex shapes from computer plans, prepare components before welding or assembly and perform various industrial repairs. This technology offers several advantages, including high cutting speed on metals, the ability to cut thick materials, good precision and a cost generally lower than laser cutting when working with thick metals. It is also compatible with a wide range of metals, making it a highly versatile process in the industrial sector.

At Ateliers BG, sandblasting is used to clean, strip and prepare metal surfaces before industrial painting or other protective coatings are applied. The process propels an abrasive at high speed to remove rust, old paint layers, residue and other contaminants. By creating a clean, slightly rough surface, it promotes better coating adhesion, improves finish quality and helps extend the service life of manufactured or repaired parts as well as metal equipment and structures.

Industrial painting consists of applying specialized coatings to metal parts, equipment or structures to protect them against corrosion, wear, chemicals and environmental conditions, while improving their appearance. This step is generally performed after sandblasting, which prepares the surface and promotes better paint adhesion. Coatings may be applied by spraying, with a paint gun or through other processes adapted to project requirements. Used in many industrial sectors, industrial painting helps extend equipment service life, reduce maintenance costs and ensure a durable, high-quality finish. At Ateliers BG, this service is integrated into the different stages of manufacturing and refurbishing metal components.

Fabrication and mechanically welded assemblies consist of designing, manufacturing and assembling structures or equipment from metal parts that are cut, machined, bent and welded together. This process combines several metal transformation techniques, including cutting, bending, machining and welding, to produce robust assemblies adapted to clients' specific needs. Mechanically welded assemblies are commonly used to manufacture frames, supports, conveyors, industrial structures, tanks and machinery components. Once assembled, parts may undergo finishing operations such as sandblasting and industrial painting to improve protection and durability. At Ateliers BG, this service supports custom projects ranging from individual component fabrication to complete industrial equipment production.

Turnkey services for industrial projects consist of managing all stages required to complete a project. This approach allows the client to entrust every phase to a single supplier, including machining, cutting, bending, welding, sandblasting, industrial painting and mechanical assembly. By centralizing these operations, the company ensures better work coordination, stronger quality control and shorter delivery times. At Ateliers BG, this service provides complete solutions adapted to the specific needs of each industrial project.
